How the Density of Your County Affects How You Vote
Social science policy researcher Colin Gordon evaluates the population density voting tendencies in the Atlantic's Cities section online. He writes, "Political scientists and party activists continue to sift through the demographic tea leaves left behind by the last election—the Democrats' white South problem, the Republicans' larger race problem, the growing generational divide. But the most striking gap between the parties is not the race or age or even income of voters. It's how close they live to each other."
In addition to the text analysis, Gordon has also made an interactive graphic of the United States' and how select counties voted in the 2012 presidential election.
